A late beta that was actually released in closed release scenes, and even before the game was released. So it was a leak of sorts. However, the download did not spread "publicly" online. Later, a remaining physical copy of the beta was publicly released.

Notes

With current disc burning and editing software, this beta can be tweaked to run more or less flawlessly. However, when it first leaked, there had been issues reported by many people in getting it to work. For example, the game wouldn't run if a memory card was inserted in slot 1 of the PS2.

Not confirmed, but there are reports that only the first 5 of the 7 levels in the final release are present.
